Description

Technical Field

[0001] The present invention relates to the field of bulk material transportation and loading, and particularly to a container bulk material conveying and loading system and a conveying and loading method. Background Art

[0002] In the process of industrial bulk material loading and transportation operations, it is a relatively common operation method to use containers to load and transport bulk materials such as coal and powders. During the process of loading bulk materials into the container, currently, most use two packing methods. Method 1: Use an independent fixed tilting machine to tilt the container. The support frame of this structure is fixed on the ground to support the tilting frame, resulting in the whole machine being unable to move over a large range, making it inconvenient to lock the container. Such a design usually also requires manual control of the overhead crane in the workshop to lift and transport the container, or use a vehicle to carry the empty container to the lower part of the fixed tilting frame, and the driver adjusts the vehicle to align the container with the locking head of the tilting frame. This method requires relatively high experience in manual alignment to complete the movement and tilting of the container before and after loading, and is only applicable to automotive containers and not suitable for railway containers (2900 high containers). Method 2, the train translation method, uses a locomotive to tow a train car carrying a container. In this way, every time two carloads of materials are received, the locomotive needs to tow and move forward, resulting in excessive occupation of the locomotive time. At the same time, during the process of loading bulk materials, because the container is placed horizontally for loading, the high-level packing building site is too wide, increasing the floor area. During the overall operation process, it is also necessary to manually open two small doors on the top of the container, and there is no automated operation process. During the overall operation process, there is also no detection and cleaning of the residual bulk materials in the container, causing pollution and waste to subsequent loading. In addition, due to the setting of more processes and the long time occupied by a single process, the overall packing efficiency is low.

[0003] In view of the above situation, how to design an automated container bulk material packing system and an automated container bulk material packing method to enable the overall operation to have functions such as automated intelligent operation, reduction of floor area, and improvement of operation efficiency has become an urgent technical problem in the industry. Summary of the Invention

[0004] The purpose of the present invention is to provide a container bulk material conveying and loading system and a conveying and loading method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A container bulk material conveying and loading system includes a container tilter for transporting and tilting the container body; a rail scale for weighing the materials in the container on the container tilter; a bulk material packing system installed on the loading floor for providing a passage for bulk materials to enter the container; a visual system for detecting and determining the orientation of the container door; and an automatic cleaning device for cleaning the inner wall of the container before loading bulk materials.

[0007] Further, it also includes a container gantry which provides the loading and unloading conditions for the container on the container tilter.

[0008] Further, the visual system for container door orientation determines the orientation of the container door of the container transported by the container gantry above the container tilter.

[0009] Further, the container tilter drives the container to perform rotational movements at angles of 90° and 180° with respect to the horizontal direction.

[0010] Even further, the automatic cleaning device performs reciprocating movements in at least two directions relative to different inner walls of the container inside the container, so as to clean the inner side of the container.

[0011] Even further, it also includes a dust removal system; the dust removal system is connected to the bulk material packing system to collect the dust generated when the bulk material packing system loads bulk materials into the container.

[0012] This invention application also provides a method for container bulk material conveying and loading, and this method includes the following steps:

[0013] Step1: Detect the orientation of the container door of the empty container to enter the loading floor for loading bulk materials;

[0014] Step2: The empty container meeting the preset conditions enters the loading process;

[0015] Step3: After entering Step2, the empty container is tilted in the Z-axis coordinate direction, and its tilting angle is 90°;

[0016] Step4: Determine the inner wall cleaning conditions for the inner wall of the empty container after Step3; it is characterized in that it also includes:

[0017] Step5: After being determined in Step4, start the loading process for the empty container meeting the cleaning conditions.

[0018] Further, in Step1, for the empty container not meeting the preset conditions, perform the following steps:

[0019] Step1-1: The empty container rotates by an angle of 180° with respect to the Y coordinate axis.

[0020] Further, in the Step5, the following operations are performed on the empty container that does not meet the cleaning conditions:

[0021] Step6: Flip the empty container so that the container door faces the bottom plane.

[0022] Still further, the following steps are further included:

[0023] Step8: Clean the inner wall of the container;

[0024] Step10: Collect and transport the bulk materials generated during the Step8 process.

[0025] Technical effects and advantages of the present invention:

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The terms "installation", "setting", "connection", "fixation", "swivel connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0038] As shown in the appended Figure 1 figures, a bulk material conveying and loading system for containers provided by the technical solution of the present invention application includes a container tilter 1 for transporting and flipping the container body; a rail scale 2 for measuring the weight of the materials in the container on the container tilter 1; a bulk material stuffing system 7 installed on the loading floor for providing a passage for bulk materials to enter the container; a visual system 9 for detecting and determining the orientation of the container door; and also includes an automatic cleaning device 3, and the automatic cleaning device 3 cleans the inner wall of the container before loading bulk materials. The technical solution of the present invention aims to concentrate processes such as loading, cleaning the container wall, palletizing, and intelligent management during the container bulk material loading process through an integrated production line design, forming an integrated operation scenario, and significantly improving the overall operation efficiency.

[0039] In the specific implementation of the technical solution of the present invention, the bulk material loading system 7 is usually installed below a large storage hopper. It includes various valves, material pipes, screw conveyors, telescopic chutes, etc., and is mainly responsible for guiding, opening and closing, and bypassing of bulk materials, and can also reduce material impact and dust emission. During the loading process of the bulk material loading system 7, the rail scale 2 measures and displays the weight of the materials loaded in the container in real time, and then compares with the preset value through the control system 12, so as to accurately match the loading weight of the container, reduce the degree of manual participation, and improve work efficiency.

[0040] As shown in the appendix Figure 1 As shown, the door orientation vision system 9 for detecting the orientation of the container door automatically starts when the empty container arrives above the container tilter 1 and is in the container delivery position, and judges whether the container door faces the direction of the unloading building; the door orientation vision system 9 can adopt existing technologies such as lasers, radars, and binocular cameras on the market to achieve the container door orientation detection function required by the embodiments of the present invention, which will not be elaborated here. After detecting the orientation of the container door by the door orientation vision system 9, its further function is to guide the direction of the container when it is placed on the container tilter 1, ensuring that the container door faces the side of the loading building, so as to shorten the overall transportation and loading process of bulk materials and improve efficiency. When the door orientation vision system 9 detects that the orientation of the container does not conform to the predetermined orientation towards the side of the loading building, it transmits data to the control system 12, and the control system 12 generates an instruction to make the container gantry 8 rotate horizontally by 180°, ensuring that the container door faces the direction of the unloading building.

[0041] As a further improvement of the technical solution of the present invention application, an aggregate hopper 4 can be added, which is used to collect the bulk materials that escape from the container during the cleaning process; and then through the connecting belt conveyor 5, which is used to transport and store the bulk materials. The dust removal system 6 performs dust removal when the bulk material loading system 7 loads bulk materials into the container and transports the bulk materials collected by the aggregate hopper 4.

[0042] As Figure 1 and Figure 2As shown, in the technical solution of this patent, it further includes a container gantry 8, which provides the loading and unloading conditions for the container on the container tilter 1. The container gantry 8 generally operates in the container temporary storage area on one side of the bulk plant, mainly responsible for delivering empty containers to the container tilter 1, and at the same time responsible for taking away the heavy containers loaded with bulk materials from the container tilter 1, and also responsible for stacking in the temporary storage area and loading containers onto trains. The door orientation vision system 9 determines the orientation of the container door of the container transported by the container gantry 8 above the container tilter 1. By enabling the door orientation vision system 9 before the container enters the loading building, the orientation of the container door can be accurately determined, so that after the container is driven into the loading building by the container tilter 1, it can be rotated in the same set direction, thus completing the preparatory work before loading bulk materials. A container landing vision system 10 can also be set up to assist in the landing positioning of the container loaded with bulk materials, so that the container can accurately stay at the predetermined position. A container stacking storage management system 11 can also be added as a system for managing the storage of heavy containers. When the locomotive has not arrived, it guides the container gantry to store the heavy containers filled by the container tilter in the temporary storage area with the optimal route, match the heavy containers and empty containers, and remember the positions of the empty containers and heavy containers, avoiding the empty running of the container gantry. In addition, a control system 12 is also set up during implementation to control each device to complete the specified actions at the set nodes, realizing automation.

[0043] In the technical solution of this patent application, the container tilter 1 drives the container to perform rotational movements with angles of 90° and 180° with the horizontal direction. When the container tilter 1 drives the container into the loading building, the container tilter 1 flips the container 90 degrees so that its container door faces the outlet position of the bulk material loading system 7 and waits to be loaded with bulk materials; when it is determined by manual or other means that there is residual bulk material on the inner wall of the container, the inner wall of the container needs to be cleaned. At this time, the container tilter 1 drives the container to perform a 180° flip, so that the container door faces the horizontal plane, and cooperates with the automatic cleaning device 3 to clean the inner wall of the container. Such a design makes the container in a vertical state before loading bulk materials, that is, the container door faces the horizontal ground or the plane parallel to the horizontal ground, thus relieving the requirement limitation of the loading building on the length dimension of the container. The loading building per unit area can accommodate more container loadings (or when a single container is loaded with bulk materials, the required area of the loading building is smaller), improving the overall space utilization rate. When the container tilter 1 drives the container to flip 180°, it is implemented when the container has flipped 90° first but needs to clean the inner wall. At this time, the container door of the container flipped 180° faces the bottom plane. After the inner wall of the container is cleaned by the automatic cleaning device 3, the container tilter drives the container to flip in the opposite direction to the 180° flip before, so that the container door faces the bulk material loading system 7 again.

[0044] In the technical solution of this patent application, the automatic cleaning device 3 reciprocates in at least two directions relative to different inner walls of the container inside the container, so as to clean the inner side of the container. The automatic cleaning device 3 extends into the container through a mechanical lifting platform, and uses brushes arranged in different directions to clean the inner wall of the container. Setting the automatic cleaning device 3 can effectively remove the residual bulk materials on the inner wall of the container. On the one hand, it can avoid the mutual contamination between different bulk material loadings. On the other hand, when loading the same type of bulk materials, the container after cleaning can achieve the maximum single loading capacity, avoiding the occupation of space by the residual bulk materials, thereby improving the operation efficiency.

[0045] It can be foreseen that dust will be generated in each different link during the entire process of loading bulk materials. The technical solution of this invention application further includes setting a dust removal system 6; on the one hand, during loading, the dust removal system 6 collects the dust generated during the process of loading bulk materials by connecting to the bulk material loading system 7; on the other hand, it is connected to the end of the belt conveyor 5 to collect the dust generated during the process of transporting bulk materials. By setting the dust removal system 6 at two different positions, it can effectively prevent dust pollution during the entire operation process. At the same time, the collected dust and bulk materials can be reused, improving economic benefits.

[0046] During use, the container gantry 8 lifts an empty container in the temporary storage area and reaches the container delivery position above the container tilting machine 1. At this time, the container door orientation vision system 9 is activated to detect whether the door of the empty container faces the container loading building. If it faces the loading building, the next step is entered. If it does not face the loading building, the container gantry 8 is started to rotate horizontally by 180° and then the next step is entered.

[0047] After the orientation of the container is determined, the container is lowered onto the container tilter 1 driven by the container gantry 8. The container tilter 1 travels to the bottom of the receiving building and first flips the container by 90° so that the container is in an upright state with the container door facing the top bulk material loading system 7. After the designed automatic container door opening program, it is judged whether the inner wall of the container meets the cleaning conditions. If cleaning is not required, proceed to the next step; if cleaning is required, the container tilter 1 flips the container 180° so that the container door faces the ground plane direction, and the automatic cleaning device 3 and the belt conveyor 5 start to operate. At the same time, the bottom cleaning machine dust removal system of the dust removal system 6 works. After the cleaning is completed, the container is flipped back 180°, and the container door faces the bulk material loading system 7 again. In the next step, the chute inside the bulk material loading system 7 extends into the container, and then the discharge valve is opened to discharge the material. At the same time, the top discharge dust removal system of the dust removal system 6 works, and the rail scale 2 at the bottom of the container tilter 1 also works. When the material reaches the preset weight value, the discharge valve is closed, the container door is closed and locked, the container tilter 1 drives the container to flip back 90°, and then the container tilter 1 travels to the transfer position. The container gantry 8 takes away the heavy container and stacks it in the storage yard. Stacking is carried out according to the route set by the container stacking storage management system 11. After the train arrives, the container gantry 8 takes away the empty container and stacks it in the storage yard. Stacking is carried out according to the route set by the container stacking storage management system 11. The container gantry 8 hoists and drops the heavy container into the train car, and the container vision system 10 ensures that the heavy container accurately falls into the train car hook.

[0048] As Figure 3 shown, a container bulk material conveying and loading method provided by the present invention includes the following steps:

[0049] A container bulk material conveying and loading method includes the following steps:

[0050] Step1: Detect the orientation of the container door of the empty container to enter the loading building for loading bulk materials;

[0051] Step2: The empty container meeting the preset conditions enters the loading process;

[0052] Step3: After entering Step2, the empty container is flipped in the Z-axis coordinate direction, and the flipping angle is 90°.

[0053] Step4: Determine the inner wall cleaning conditions of the inner wall of the empty container after Step3; characterized in that, it further includes:

[0054] Step5: After the determination in Step4, start the loading process for the empty container meeting the cleaning conditions.

[0055] In the technical solution of the present invention application, in Step1, the following steps are executed for the empty container not meeting the preset conditions:

[0056] Step 1-1: The empty container rotates by 180° with respect to the Y coordinate axis.

[0057] In the technical solution of this invention application, in Step 5, the following operations are performed on the empty container that does not meet the cleaning conditions:

[0058] Step 6: Flip the empty container so that the container door faces the bottom plane.

[0059] In the technical solution of this invention application, the following steps are further included:

[0060] Step 8: Clean the inner wall of the container;

[0061] Step 10: Collect and transport the bulk materials generated during the process of Step 8.

[0062] During the process of bulk material transportation and loading operations of containers, generally, the container is directly filled and then towed and transferred. The overall process is complicated and the production efficiency is low. In the technical solution of this invention application, by first detecting the orientation of the container door before the container enters the loading process in Step 1, after the containers with the same door orientation enter the loading process in Step 2, they can quickly align with the bulk material loading mechanism by flipping, realizing assembly line operations and improving the operation efficiency. By setting the process of determining the cleaning conditions of the container in Step 4, and then determining whether cleaning operations are required, this process can effectively remove the residual bulk materials on the inner wall of the container. On the one hand, it can avoid cross-contamination between different bulk material loadings. On the other hand, when loading the same type of bulk materials, the cleaned container can achieve the maximum single loading capacity, avoiding the occupied space by the residual bulk materials, thereby improving the operation efficiency. After the orientation of the container door is detected, if the door orientation meets the preset direction, no adjustment is required, and at this time, the rotation angle of the container with respect to the Y coordinate axis is 0°. If the door orientation does not meet the preset direction, through the process of Step 1-1, the container is driven by an external force to rotate by 180°, and then the container is repositioned to prepare for entering the loading process in Step 2.

[0063] In the technical solution of the present invention, through the process of Step 3, the empty container entering the loading building is flipped in the Z-axis direction, and the flipping angle is 90°. The purpose of this is that after the container enters the loading building, the process of changing from horizontal to vertical is first completed by an external force, so that the container door faces upward when it is vertical. At this time, a 90° rotational movement is performed with respect to the Z-axis. Then, the cleaning condition determination Step 4 is carried out. The main purpose of the process of Step 3 is to make the container in a vertical state before loading bulk materials, that is, the container door faces the horizontal ground or a plane parallel to the horizontal ground, thereby removing the requirement limit of the container on the loading building in terms of length dimension. The loading building per unit area can accommodate more container loadings (or when a single container loads bulk materials, the required area of the loading building is smaller), improving the overall space utilization rate.

[0064] In the technical solution of the present invention application, through Step 8, the inner wall of the container that does not meet the cleaning conditions is cleaned; and through Step 10, the bulk materials dropped during the cleaning process of the inner wall of the container are collected. The cleaning process of Step 8 can effectively remove the residual bulk materials on the inner wall of the container. On the one hand, it can avoid cross-contamination between different bulk material loadings. On the other hand, when loading the same type of bulk materials, the cleaned container can achieve the maximum single loading capacity, avoiding the residual bulk materials occupying space, thereby improving the operation efficiency. The collection of bulk materials can prevent the bulk materials from accumulating under the loading building and affecting container transfer, and at the same time, the recycled bulk materials can be reused.

[0065] In the technical solution of the present invention application, through Step 10, corresponding dust removal treatment is carried out on the collected bulk materials at different conveying positions, which can reduce the dust hazard and air pollution.

[0066] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
